If that's what the reason he would have convinced sai to not go by saying we will live seperately for few days or will send pakhi to her house instead of calling her words like family breaker, orphan, burden. He wanted her to forgive pakhi so easily. He don't even have guilty for bailing a criminal like pakhi, acted like sai is over reacting.
If he bailed pakhi for kaku, why did he never held pakhi responsible for her crimes. Shouldn't he be distant with pakhi, instead he was singing praises saying what a great friend she was even before vinu come into picture.
Well that is mystery something happens that he doesn't consider her as pakhi that's why he called her as patralekha unlike before
So switching from pakhi to patralekha is her punishment from him.
Making her his wife, singing praises for her, telling her sorry for thousand times, doing husband duties (except consummation), acting like she never did any crime all are nothing.
Great 👍.
